To all whom it may concern:

Be it known that l, CHARLES M. Cininnn,

a citizen oi' the United States, residing at Pittsburg, in the county of Allegheny and State of' Pennsylvania, have invented eer-` :tain new and useful Improvements in Coke- Draw'ing Apparatus, oi' which the iollowing is a specification, reference being had there-ii;

to the accompanying drawing, loi-ming` part of this specification in which* Figure 1 is a view in side elevation oi' my improved coke drawingfapparatus, showing` it'mounted upon overhead supporting tracks and in position in front oi an oven. Fig. 2 is a'horizontal sectional view onthe line'il. il. .oi Fig. 1. Fig. 3 is a detail `view showing a beam provided with a hinged rake head. Fig. 4 is' a view in elevation from the back, looking toward the oven. Fig. 5 is a view in front elevation oi' a series oi coke ovens provided 'with a receiving conveyer arranged A :longitudinally in iront of the doors.

- is a plan view ol' Fie. 5.

Fig. 6 Fig. 7 is a view in side elevation, part y in section, similar to Fig. 1, showing the machine mounted upon .supporting ground tracks in working position vin front oi an oven, and provided with a search light. Fig. 8 is a view in elevation from the back, looking toward the oven.

My invention refers to the class oi' apparatus for drawing coke i'roin an oven, or l'or performing any similar operation, and is designed for the purpose of providingI such an apparatus adapted to be supported by and Av transported along tracks arranged in .l'ront ol' ga bank of ovens or retorts.

In general, the invention comprises an active element consisting oi rake beam or seraperadapted to be projected into and withdrawnfrom the oven and means l'or pro- ,dueing` said movement, together with nieans for supporting the beam, elevating; or dos pressing it to vary the height ol the scraper,

the operative elements by means oi' mech-- means for dei'leeting the beam laterally so as t0 rtliich all parts of the4 oven on a horizontal plane, with means 'for moving,` the apparatus along in front oi' the oven to facilitate such adjustment yoi thebeain, and also to shii't it from one oyen toV another.

l n These various movements' are designed to kbie/imparted to anisin under the control oi' an operator mounted upon the traveling .fn'riage' The machineamay alsolinclude =iiec`l1anism .by l

which the coke is carried away and delivered to any suitable point after having been withdrawn from the oven.

The prosentapplication comprises in part a continuation loi' my prior application tiled longitudinal and vertical movement toA the.

extractor. v

iel'erring now to the drawings, A. represents a carriage constructed in any suitable or` preferred manner, and supported by means oi' wheels 2 upon rails 3, carried by any suitable su ppoitingy l'ran'iework et, eX- tendingI outwardly in iront ol the upper portion oi the oven structure 5.

i B is a turntable rotatably mounted upon the carriage A as by means oi casters or rollers 6 supported upon the lower portion oi' the carriage 'framing or upon the turntable. Depending downwardly from theturntable B is a ira-ine 7, made oi' plates or other suitable material'adaptedto provide a rotatable support l'or the scraper beam 8 having,` the downwardly extending rake or scraper at` the iront end.

in Fig'. 3 l have shown a inodiiied constructionoi' scraper, pivotally mounted in the end ol' the beam so as to allow it to i'oid upwardly in entering,r the restricted door opening over the cokeand 'provided 'with a springl S adapted to automatically erect the beam to operative position. This construe tion conforms to the rake device shown and iesoribed in the liebb patent' referred lto ater.

The beam 8 is incorporated with. or mounted between the sides of the framing 7, in

which is also mounted a driving sha'l't Q car rying a pinion l() in engagement with a rack 11, forminga portion of the rake beam 8. The pinion 1() is adapted to be rotated in one direction or the other by any suitable mechanism, and have shown a reversing motor 12 mounted on the depending framework 7 and geared with the pinion 10, by suitable reducing gearing as indicated in Figs. l and 4. Any other suitable means by which longituditial movement may be imparted to the beam may be substituted for the rack and pinion.

For the pur ose o f raising or depressing the scraper en of the beam I have providedv a vertically movable frame 13, adapted to engage the beam from below and above by means of rollers 14, 15, such frame being adapted to be raised or lowered by any convement.means mounted upon the turntable provided a reversible inotor 18, adapted to 'as clearly shown.

actuate a pinion 19 engaging an annular rack 20, secured to the relatively stationarycarriage A.

For the purpose of transporting the entire mechanism along the tracks 3 one or both axles may be driven through the usual toothed gearing as shown, by a reversible motor 21, mounted in any suitable position upon the carriage framework, in the well lqiown manner of traveling cranes. The various motors 12, 16, 18, and 21 are geve'rned by suitable controllers 22, located in a pulpit 23, depending fromthe turntable B These controllers, preferably one for each motor, are within reach of theoperator carried by the pulpit, and it will be seen that each of the various functions of the diierent elements may be thus separately governed and controlled by him. It will be observed that the operators pulpit is so located that he may readily see .and observe the interior of the oven and thereby 4accurately direct and manipulate the beam and scraper.

24 is a conveyer located in front of and adjacent to the oven and adapted to receive the coke and to convey it to any suitable receiving vessel as a car, either directly, or through a supplemental conveyer 25, located approximately at right angles to conveyer 24 and adapted to receive the coke therefrom. Both of these coiiveyers, if carried bythe carriage, are driven at their proper speeds by means of suitable mechanism, as sprocket gearing, actuated by a separate constantly running motor 26. It is obvious however, that one continuously running motor might be mounted upon the carriage and that the various movements to perform the different functions may be taken therefrom through suitable gearing, shafts, and clutch mechanism by means of proper levers within the control of the operator. I do not desirel therefore to be limited to the'eniployment of separate motors, or in fact to any particular i design or typel of power-imparting means, since it is obvious that various substitutions in the way of prime movers or power generl it maybe made of any practicable length de- I sired and continuously arranged along in front of the oven doors as shown. This conveyer 24 may discharge directly into receiving cars or other vessels at its end, or into a supplemental conveyer 25 arranged at an angle to the main conveyor and adapted to convey the coke to cars located on the usual tracks in front of the oven yard. lith either construction the carriage is relieved of the weight and necessity of driving the conveyers, and will operate to draw the coke out upon the receiving one which then conveys it away as described, it being understood that the conveyers are fixed driving means.

An advantage of electric motors is that the current may be continuously supplied through the well known trolley system in common use.

The operation of the apparatus will be readily understood from the foregoing description. The carriage is moved from one oven to the other and stopped in front of an oven ready to be drawn. vided with the rake at its front end, which maybe rigidly connected or pivotally connected as shown in Patent 7277 granted to John A. Hebb,'is then projected inwardly over the top of the coke, being sulheiently raised by the mechanism described, until sufficiently far advanced in the oven to engage a body of coke to b e drawn. The rake is then depressed downwardly into engagement with the coke and when so engaged, power is imparted to the bea-in in a reverse direction, causing it to travel outwardly, drawing with it a section of coke which is'delivered upon the conveyer 24.

When it is desired to i'each in toward the right or left of the oven, the turntable B is partially rotated so as to vary the horizontal angular position of the beam, its longitudinal and vertical adjusting functions being performed in the same I nanner as already described at whatever angle the turntable and its supporting framework may assume.

For the purpose of bracing the apparatus. to counteract the strain of pulling against the mass of coke, a rail 27 is located along the provided with their own The beam pro supported carriage as shown in the principal drawings, will not always be necessary in order to secure these desirable results, but that other arrangements or designs of beam supporting and manipulating means may be employed with the carriage to provide a pend ently carried beam, as by mounting the carriage on ground tracks and extending it upy wardly above the,oven door level to provide an overhead turntable support.

In Figs. 7 and 8 I have illustrated such construction, and also shown the machine as provided with a lighting device. ln these drawings A represents the'carriage constructed in any suitable or preferred manner, mounted bywheels 2 upon rails 3 carried by any suitable support as ties 4 in front of the oven 5, yand sup` porting the superposed rotatably mounted turntable B by casters or rollers 6, the turntable having the depending frame 7 and the other elements, indicated by corresgpnding numerals and arranged. to operate in the manner already described.

For the purpose of illuminating that por tion of the oven and its contents to which the extracting element of the beam is directed to withdraw a section. of' the coke, I have provided a search light 29 mounted in any suitable manner as by a supporting frame 3() eX- tending outwardly in front of the framework 7 at each side ofthe lifting mechanism 1'3 or otherwise and preferably adapted to be ad-` iusted therein to properly locate the rays and direct them to the back or darker -portion of the o'ven, in alinement with the beam and.l its path. The adjustment may beet fected by any suitable means as nuts 31 adapted to 'xedly securethe .pivotal trunnion bearings, as will be readily understood,

while. the mounting of the search light in frame insures its lateral movement with the lateral movement of the frame 7 depending below the turntable, and resulting lateral adjustment of the beam 8, whereby the rays a will always be maintained inV aline' ment with the beam, corresponding to its working path at any position in the oven.

lt will be understood that current for the Search light, as for the motors, may be supplied by suitable connections and the usual trolley apparatus from any producing point.

The advantages of the search light will be aappreciated by those familiar with this class apparatus as it obviates the objections ol obscurmg the work in the oven due to darkness, vapor, etc.

From the foregoing descriptionit will be seen. that lf secure a further considerable advantage in; supporting the beam below the turntable by a carrying structure which in turn is supported and laterally adjusted by the turntable, for the reason that the working mechanism, being located above or overhead, the parts at or below or level of the oven doors are reduced to a minimum, thus giving the operator a non-obstructed view and ample space.
